------------------------------
Summary: Provide access to select statement's real column
definitions
Key: CASSANDRA-9532
URL: https://issues.apache.org/jira/browse/CASSANDRA-9532
Project: Cassandra
Issue Type: Improvement
Reporter: mck
Assignee: mck
Currently there is no way to get access to the real ColumnDefinitions being
used in a SelectStatement.
This information is there in
{{selectStatement.selection.columns}} but is private.
Giving public access would make it possible for third-party implementations of
a {{QueryHandler}} to work accurately with the real columns being queried and
not have to work-around column aliases (or when the rawSelectors don't map
directly to ColumnDefinitions, eg in Selection.fromSelectors(..), like
functions), which is what one has to do today with going through
ResultSet.metadata.names.
This issue provides a very minimal patch to provide access to the already final
and immutable fields.
